The following patchset introduces Device Tree quirks which apply right after unflattening. Quirks allow using a single device tree blob to support revisions of a single board.
This makes deployment easier, since there is no need to modify the bootloader environment, and allow booting using a very small bootloader shim with a resulting decrease in boot time which is extremely important in various use-cases.
For details please look at Documentation/devicetree/quirks.txt
This patch has an implicit dependency on a previous patch "of: Custom printk format specifier for device node" for debugging prints of device nodes.
